Just to extend the World's Longest Thread a little longer, I'll bite. I recently picked up a 1986 BTA90, not knowing what it was (I hadn't had a pistol since at least the early 1970s) but it looked well made and was the right size. Based on the small number of rounds I've run through it, and taking it apart & putting it back together, I'm very pleased with it. It fits my hand like it was made for it, and has just the right amount of weight and recoil - and it's accurate enough that anything I miss is my fault, not the pistol's.
Can't really understand why they don't bring a higher price (I paid $250 for this one in barely-used condition), but I'm happy with the purchase. It certainly seems to beat anything new in that price range.....
